Multiple Ethernet Interfaces

I've set up a RH9 box as follows:

eth0: IP address of, with gateway of
eth0: no IP, promisc mode (for Snort)

Whenever the machine reboots, the route table shows the default route assigned to eth1, leaving the Internet inaccessible. I have to manually assign the default route to eth0 every time.

How do I make this change permanent? I'm happy to RTFM, but I haven't found the right resource that tells me how to properly configure two Ethernet interfaces.

Several ways to do this...

Hi -

You should be able to set up everything you need from the "Network Configuration" GUI. Unfortunately, I'm running SuSE Linux (which has a different GUI, "YaST2"), so I can't offer you any specifics.

Your best bet is to use "ifconfig" to determine what's going on (for example, "man 8 ifconfig" or "ifconfig eth0").

On SuSE, the "persistent configuration" created by the YAST2 GUI and read by during SuSE boot is contained in the directory "/etc/sysconfig/network". I'm not sure where your equivalent "local configuration" text files are located on RH9, but they're probably under "/etc" and they're probably not too difficult to find.

'Hope that helps .. PSM
